Additionally, you will save over a 1.5 tonnes of carbon dioxide every year.
*Returns based on south facing roof with a 39 degree pitch and no shading.
**20 year total benefit is based on 3.2% inflation and 6% energy inflation.
3.2% inflation is based on as an average over the last ten years from the “Office of National Statistics Consumer Price Indices”. 6% fuel inflation is based on an increase of fuel prices over the last 5 years sourced from “DECC Domestic Energy Price Statistics”

Solar Battery Storage
Solar, alone, already provides you with phenomenal savings on your energy bills; couple your solar system with battery storage and you can achieve even further savings!
By investing in battery storage, you will also decrease your dependence on the grid, achieve massive cost savings, and even further lower your carbon footprint!

Battery StorageEnergy Diverters
Save even more money using an energy direction control device!
Energy diverters are an intelligent addition to any solar PV system.
They take the excess energy produced by the Solar PV system that would ordinarily be exported back to the grid, and diverts it to designated heat appliances i.e. your hot water cylinder.
On average, you can receive 4p for every kilowatt of Solar PV energy that you export to the grid; comparatively, on average, it costs up to 18p per KwH to heat your hot water, with electricity.
With one of the Energy Diverters installed by Impact you can use your excess energy to heat your hot water, saving you that huge difference!
